The `recvContent` function attempts to optimize performance by pre-allocating memory for the message body based on the `ch.header.Size` field, which is a 64-bit unsigned integer (`uint64`).\n\n```go\n// channel.go:495-496\nif cap(ch.body) == 0 {\n    ch.body = make([]byte, 0, ch.header.Size)  // unbounded\n}\n```\n\nThe underlying library fails to validate or cap this requested size against any upper boundary—such as the maximum frame size negotiated during connection establishment (`FrameMax`). If a server specifies an extreme body size (e.g., `2^62` bytes), the Go runtime attempts to allocate an exabyte-scale slice capacity. This immediately exhausts available system memory, causing the operating system's OOM killer to terminate the application.\n\n**Attack Vector / Exploitation Scenario**\n\n- Message Delivery Phase: A malicious or compromised AMQP broker sends a standard `basic.deliver` frame containing a content header with an intentionally inflated `body-size` variable.\n- Authentication Requirement: No special privileges or authentication bypasses are required; the crash occurs seamlessly during normal message consumption.\n\n**Impact**\n\n- Availability: High. Exploded memory consumption results in an instant process termination, destroying application state and availability for all threads sharing the environment.","state":0,"publishedAt":"2026-09-17T17:04:20+00:00","modifiedAt":"2026-10-01T20:56:22.8051831+00:00","affected":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.13.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-r9c8-gcjp-xfwh","https://nvd.nist.gov/vuln/detail/CVE-2026-77410","https://github.com/rabbitmq/amqp091-go/pull/346","https://github.com/rabbitmq/amqp091-go/commit/91b65fa0096a99a580cf51a31b24028ff1c60382","https://github.com/rabbitmq/amqp091-go","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"],"sourceUrl":"https://github.com/advisories/GHSA-r9c8-gcjp-xfwh","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-r9c8-gcjp-xfwh","identifiers":["GHSA-r9c8-gcjp-xfwh","CVE-2026-77410","GO-2026-6500"]},"retained":false,"historicalAffected":[]},{"revision":"da2a78447c644b4594bf86e268b0a87f","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6500","aliases":["CVE-2026-77410","GHSA-r9c8-gcjp-xfwh"],"title":"RabbitMQ amqp091-go: Resource Exhaustion (OOM) via Unbounded Body Buffer Allocation in github.com/rabbitmq/amqp091-go","description":"RabbitMQ amqp091-go: Resource Exhaustion (OOM) via Unbounded Body Buffer Allocation in github.com/rabbitmq/amqp091-go","state":0,"publishedAt":"2026-10-01T20:23:56+00:00","modifiedAt":"2026-10-01T20:45:11.275893+00:00","affected":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.13.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-r9c8-gcjp-xfwh","https://nvd.nist.gov/vuln/detail/CVE-2026-77410","https://github.com/rabbitmq/amqp091-go/commit/91b65fa0096a99a580cf51a31b24028ff1c60382","https://github.com/rabbitmq/amqp091-go/pull/346","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6500","license":"OSV · upstream source license applies","key":"osv:GO-2026-6500","identifiers":["GO-2026-6500","CVE-2026-77410","GHSA-r9c8-gcjp-xfwh"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
